Product Overview

B1‑AF100‑NA is electro‑pneumatic positioner receiving 4‑20 mA control signal from DCS/PLC to precisely position linear pneumatic valve actuator. It converts electrical control signal into pneumatic output pressure to drive valve stem, realizes closed‑loop valve‑stroke positioning. Widely applied for flow, pressure and temperature regulating control loops. Surplus and refurbished tested spare valve positioner for control‑valve maintenance projects.

Application Notes

‑ Perform stroke calibration after installation. ‑ Supply clean dry instrument air to prevent internal nozzle‑blockage. ‑ Typical deployment: Linear control‑valve electro‑pneumatic positioner spare‑part stocking.
